I've had no problems since having Fibre 250 installed around September 2020 until around 2 months ago (late March) since when I've been getting "ERROR_NO_CARRIER" messages, firstly around once a week, then more recently daily, eventually with dropping of line speed. Three weeks ago my usual d/l speed of 265MBit/s dropped under my guaranteed 150MBit/s so I raised a call via My BT, which came back as Fault fixed after a few days. Nothing changed. My speed continued to drop so I raised another call, this time using the text service. An engineer visit was arranged and he came, said he could see there was an issue but didn't know what it was, replaced the terminators in the grey box outside the house and reset the line. Speed was back up to 265MBit/s. However, the almost daily disconnect has continued and I'm now down to 125MBit/s (again under my guaranteed speed). Generally the disconnects have been between 01:00 and 05:00, but tonight occurred around 22:00.
I've done the usual stuff of disconnecting everything at my end, including from the phone line (DECT phone and Sky+ box), but still it drops, therefore I'm sure it's either my Smart Hub 2 (the drops seemed to start not long after a f/w update on 21st March, but are still here after another update last week) or the incoming line (somewhere). Although I believe FTTP is listed at my cabinet (Chelmsford, No72) I'm not offered the chance to upgrade as one way of fixing this.
So, is there any way I can get this fixed properly (swapping wires in cabinet or whatever can be done) and permanently ? I really would like to get back to the reliability I used to have and the speeds which I increasingly need for leisure and work as I won't be returning to an office anytime soon. If I need to post Call refs, logs from Hub, etc, please let me know what is wanted, and what to do with them.
Thanks.
